The package IO provides several classes for the serialization of geometry-data. Because of its performance and the rich information it preserves the Geometry2DConverter is the standard converter for Geometry2DAdapter-objects. Other converters for geometric-data can be found in the sub-package experimental. Their use is discouraged because of their weak performance.

The package also includes classes for simple file-handling, that is for writing and reading whole sets of Geometry2DAdapter-objects to and from files.
